There might be cases where you describe an enum in isaspec and want it to use
for decoding but also for codegen with e.g. mako.
Lets have a look at the following exmaple:
<enum name="#cond">
<value val="0" display=""/> <!-- always: display nothing -->
<value val="1" display=".gt"/>
...
</enum>
In the decoding case we want that nothing gets displayed if #cond has the value of "0". For
codegen with mako this could result in the following C code:
enum PACKED cond {
COND_ = 0,
COND_GT = 1,
...
};
What you really want is this:
enum PACKED cond {
COND_ALWAYS = 0,
COND_GT = 1,
...
};
To make this possible introduce BitSetEnumValue class which represents
an isaspec xml enum. It holds the value, displayname and now a name.
With the __str__ method the old behaviour is still intact.
